There's a rather old and neglected mod. The Etruscans fit in there. They could have been as late Etruscan as Early Romans.

So useless, if a man is able to work, he is able to carry a weapon 

I'm from France. Okay, I'll create a discussion and share you the link  so that you can help with my project ! I understand what you mean but, yeah, I'm not a real artist but I love learning about historical periods or civilisations so I 'd like to create mine... It may (instead surely) be not deepened and not finished but that's the idea of making a discssion where players could share their expericences and improving ideas for my mod !! And, I want to start with the Etruscans, which is a Greek-Roman civ : it's easier (but harder too because must find their own specifics features !)...
